Route Overview:

The Princes Highway forms a major part of Highway One, along the eastern and southern coastlines of Australia between Sydney and Adelaide. Within NSW it carries, for the most part, the National Route 1 shield, as well as shorter sections with the State Route 60 and Metroad 1 shields in Wollongong and Sydney. At its northern terminus, the highway carries State Route 54, but then reverts to being unnumbered between Newtown and Kogarah. The Princes Highway is the backbone of the NSW south coast, being the major road south to Wollongong and Nowra, and the only road south from there.
